UNJEF 12 Point Screws

Another weird and wonderful order was received recently for some 12 Point Flange Nuts and Screws in Black Oxide for the aerospace industry.The customer specified UNJEF thread which is a very unusual thread form. UNJEF are ultra fine pitch threads. The thread accuracy is referred to as a 3B class of fit or a 2B class of fit.Normally we take days to complete our standard jobs, but this part took 3 weeks due to its complexity.#engineering #fasteners #manufacturing
